Video Subtitle Remover Pro v3.22.0

What's changed

• Brings the native workbench closer to the approved premium mockup with a larger 16:9 preview, 17:8 preview/inspector split, static Preview heading, and four flat inspector disclosure rows.
• Moves preview utilities into mouse and keyboard context access, leaving the first viewport calm and media-first.
• Replaces the legacy queue action cluster with functional Add, Remove, Clear completed, and move up/down controls; compact layouts consolidate them into one menu.
• Reduces the footer to one status line while keeping Activity available through Ctrl+L and context menus.

Verification

• 916 tests passed, 3 skipped, 12 subtests passed.
• Hidden scaling probes passed at 100-200% across English, pseudo-localized, RTL, default, and high-contrast modes.
• Strict frozen build, installer smoke, reference corpus, FFmpeg smoke, dependency audit, SBOM, and advisory gates passed.

The Windows artifacts are unsigned. Verify downloads with SHA256SUMS.txt.

Video Subtitle Remover Pro v3.21.0

Video Subtitle Remover Pro 3.21.0 delivers a calmer, command-first desktop workbench. Primary setup stays in one compact toolbar, typography is larger and more readable, the inspector uses separator-led disclosure instead of repeated controls, and secondary preview tools are grouped behind one contextual action. The empty queue now contracts to a single row, slider values are borderless, and the status surface is intentionally quiet.

The redesigned shell follows the new v4 visual target while preserving the existing cleanup workflow, responsive stacking, keyboard access, high-contrast theme, pseudo-localization, and RTL behavior.

The Windows x64 portable and installer artifacts were rebuilt through the strict local release pipeline. The full suite passed with 916 tests, 2 skips, and 12 subtests; frozen launcher smoke, installer smoke, the 10-clip reference corpus, dependency audit, advisory policy, SBOM generation, and checksum verification also passed. FFmpeg 8.1.2 was used for external-runtime verification.

The Windows binaries are currently unsigned; verify downloads with SHA256SUMS.txt.

Video Subtitle Remover Pro v3.20.0

Video Subtitle Remover Pro 3.20.0 completes the premium workbench refresh with a compact command bar that keeps media import, cleanup profile, subtitle region, output, and Start cleanup above the preview. The preview and inspector now share a flatter, denser workspace with clearer type hierarchy, fewer status pills, quieter borders, and tighter spacing.

This release also introduces a new restoration-frame application mark across the README, window chrome, packaged EXE, Windows icon, and About dialog.

Video Subtitle Remover Pro v3.19.1

Video Subtitle Remover Pro 3.19.1 delivers the redesigned premium desktop workbench: a compact command strip, clearer type hierarchy, calmer surfaces, denser control grouping, and a focused job monitor with less explanatory chrome.

This release also refreshes Windows x64 portable and installer artifacts from the strict local release pipeline. Frozen launcher smoke, the 10-clip reference corpus, dependency audit, advisory policy, SBOM generation, and checksum verification all passed. FFmpeg 8.1.2 was used for external-runtime verification.

Video Subtitle Remover Pro 3.19.0

Highlights:

• Selectable OCR engines, opt-in subtitle-language mask filtering, and live OCR feedback during region drawing.

• Detection-efficiency and color-preservation evidence in GUI/CLI batch summaries and sidecars.
• Major controller, CLI, settings, frame-timing, processor-loop, and import-graph refactors with preserved behavior.
• Hardened tracked-spec release pipeline with frozen/installer smoke tests, SBOM, advisory evidence, and dependency audit.

Verification:

• Complete source suite passed in the release pipeline.
• Frozen startup and silent installer-payload smoke passed without foreground UI.
• Strict dependency audit: 0 vulnerabilities, 0 skipped packages.
• Unsigned Windows artifacts; verify against SHA256SUMS.txt.

VideoSubtitleRemoverPro v3.18.1

Standalone Windows x64 build of Video Subtitle Remover Pro v3.18.1 (default RapidOCR/ONNX profile). Fully local — no cloud, no account.

Highlights

Fixed

• Frozen build now launches cleanly. numpy 2.x is packaged with --collect-all and UPX is disabled, resolving a ModuleNotFoundError: numpy._core._exceptions crash at startup.
• Accurate --start/--end time-range seeking on CFR long-GOP sources (grabs forward to the exact frame instead of snapping to the nearest keyframe).
• ONNX LaMa / MI-GAN now binarize the mask before inference, so anti-aliased masks no longer produce partial-strength fill.
• Unhandled Tk callback / .after exceptions are logged with a full traceback instead of a bare stderr dump.

Changed

• Internal decomposition of the process_video pipeline (_resolve_frame_range, _finalize_and_mux, _emit_quality_report) — no behavior change, verified against the real-ffmpeg reference-clip, VFR, and checkpoint/resume suites.
• Unified post-inpaint finishing (edge-ring colour match + feather) across all inpainter backends.
• Dependency-floor consistency guard across requirements.txt, dependency profiles, and release verification.

Security

• Single-source libpng CVE floor in backend.security_checks (no more drifting 1.6.54 literals).
• Hidden, bounded, shell-less external-process policy for every production backend child.

VideoSubtitleRemoverPro v3.17.1

What's new in v3.17.1

Detection & OCR

• RapidOCR 3.x support -- lifted pip cap from <3.0.0 to <4.0.0; hardened constructor and output parsing for v3.x API changes
• PP-OCRv6 auto-selection -- PaddleOCR 3.7+ defaults to PP-OCRv6 (34.5M params, +5.1% accuracy, 5.2x CPU speedup, 50-language single model)
• Vertical text detection fix -- coordinate mapping after 90-CCW rotation was mirrored/swapped; boxes now placed correctly

Security

• VSR_SEEDVR2_CMD now uses shlex.split() to prevent argument injection via environment variable
• Crash reporter path regex extended to handle paths with spaces (prevents partial username leaks)
• Support bundle restricts collected paths to safe file extensions (.json, .md, .txt, .log)

Reliability

• Fixed preset save crash (BUILTIN_PRESETS and _load_user_presets missing imports)
• Fixed crash in queue item elapsed-time display (missing datetime import)
• Fixed CAP_PROP_FRAME_COUNT returning -1 bypassing the fallback (used max(1, ...))
• Catch TclError alongside RuntimeError when posting to Tk from worker threads
• A/B scrubber releases VideoCapture objects even if window construction fails
• JSON log handler now properly closes its file handle
• Corrupt settings.json backed up to .bak before resetting to defaults

UX

• "Set region" button now appears directly in the preview action bar
• Preview height increased from 158px to 260px
• Drop area shows accurate text when TkinterDnD2 drag-drop is unavailable
• Status badge, progress bar, and accent stripe now forward clicks in queue cards
• ModernButton.set_enabled(False) resets stale hover/pressed state
• GitHub issue templates with OS/GPU fields and feature request form

Build

• CycloneDX SBOM (sbom.cdx.json) generated in release builds
• ProPainter mode documented as TBE+LaMa hybrid (not upstream NTU S-Lab weights)
• Architecture docs refreshed for post-module-split tree

VideoSubtitleRemoverPro v3.16.0

Automated build for v3.16.0.

Highlights

• RTX 50-series (Blackwell) support. setup.py now auto-detects 50-series cards (5050–5090, RTX PRO 6000, B100/B200/GB200) and installs PyTorch from the CUDA 12.8 (cu128) index. Older cu118/cu121 pins have no sm_120 kernels and error out or fall back to CPU.
• Fixed a stale torch==2.7.0 README pin that conflicted with the torch>=2.10.0 floor (CVE-2026-24747).
• Documented TV / limited color-range handling (preserve_color_metadata, on by default).

Which download do I want?

• GPU users (especially RTX 50-series): run from source — clone the repo at this tag and follow the install steps so PyTorch lands on the right CUDA wheel (cu128 for Blackwell). The attached ZIP is a CPU-only PyInstaller build and will not use your GPU.
• CPU users / quick try: VideoSubtitleRemoverPro-v3.16.0-windows.zip is a self-contained Windows build — unzip and run VideoSubtitleRemoverPro.exe.

Note on antivirus / SmartScreen

This ZIP is an unsigned PyInstaller bundle that ships CUDA/torch and fetches model weights on first run. AV engines and SmartScreen commonly flag that pattern heuristically (large packed binary + network calls) as a false positive. Downloaded model weights are verified against vendored SHA-256 hashes. If your AV flags it, that's the heuristic — verify the ZIP hash and run from source if you prefer.
